This guy capture Hyena cubs and train them, but they’re wild animals. I don`t think than he can train them to protect and guard. They could really hurt some one (including the owner). Adults measure 95.0—165.8 cm in body length, and have a shoulder height of 70.0–91.5 cm. Spotted hyenas in Zambia, with males weighing on average 67.6 kg (149 lb), and females 69.2 kg (153 lb).
